NFS Resource Monitor Process

Before starting the resource monitor probes, all shared paths are read from the dfstab file and stored in memory. In each probe cycle, all shared paths are probed in each iteration by performing stat() of the path.

Each resource monitor fault probe does the following:

1. Sleeps for Thorough_probe_interval.

2. Refreshes the memory if dfstab has been changed since the last read.

3. Probes all shared paths in each iteration by doing stat() of the path.

If any path is bad, the resource status is set to FAULTED. If all paths are working, the resource status is set to ONLINE again.
